The Effect of Problem-Based Learning with STAD Setting on Junior High School Students’ Mathematical Problem-Solving Ability

Abstrak

The aim of this study was to examine the effect of implementing the Problem-Based Learning (PBL) model with a Student Teams Achievement Division (STAD) setting on students’ mathematical problem-solving abilities and to describe the implementation of the learning process during the study. This study employed a quasi-experimental approach with a Posttest-Only Control Group Design. The research sample consisted of two eighth-grade classes at SMP Negeri 1 Tongkuno selected through random sampling. Class VIII-1, consisting of 26 students, was assigned as the experimental group, while Class VIII-3, consisting of 25 students, was assigned as the control group. The research instruments included observation sheets and a mathematical problem-solving ability test. Data were analyzed using descriptive and inferential statistics. The findings indicated that the implementation of the Problem-Based Learning model with a STAD setting was conducted effectively and contributed to improved learning implementation and active involvement of both teachers and students throughout the learning process. The findings also revealed a difference in mathematical problem-solving abilities between the two groups, with the experimental group achieving a mean score of 76.15, compared with 69.40 for the control group. Furthermore, the hypothesis testing results showed a significance value of 0.0465 (< 0.05), indicating that the implementation of the Problem-Based Learning model with a STAD setting had a positive and statistically significant effect on the mathematical problem-solving abilities of students at SMP Negeri 1 Tongkuno.
